Part II : how has the id been hacked!

This part will speak about the way I explored gmail and got to know the various ways of hacking it!
so.. this is how i started. go through each and every section of gmail. check out every field, say secondary email and stuff like that.
if you go see, in the settings page you have some option called forwarding and pops.. there you've got this option of forwarding, when you enable it and add a mail id, a copy of every mail which you get in this particular id will be forwarded to the id which you specify in that field!
so, when I was finding out such things, I was stunned to see this forward option enabled with this mail id from which I had got 'adult' related mails during certain period, say that was the time when I got into this internet world.
That was the time when I was not aware of these junk ids and crap sites which try to earn through getting people into the adult world! So, one day i got a mail of this kind:
Dear user,
you're one of the lucky winner who has been selected by our core team. You can anytime come back to us regarding any advice or help which you would require in your day-to-day life! We're here to help you.

Me who was as innocent as moondram pirai sri devi went ahead and first wrote a thank you mail. Then never wrote to that id. After few days I again got a reminder mail which was almost like I have to ask something. I again, a stupid wrote back, what is 'engineering' :D
crap..
got a reply which was a big damn story, thought they've really written back about Engineering and went ahead reading! Damn it..!!! it was an adult story; believe me.. i read only the 1st four lines which clearly defined that the story is about the adult relationship between a son and a mother!!
fuckers! i'm getting real bad words which are the worst in the entire world of vocabulary...
stopped reading there. then too i was not aware that it was an individual who was trying to ruin my life! wrote back to that id, please unsubscribe me..
damn reply was full of porn pics! somehow got rid of that $hit later then..

now coming back to the story of finding the enabled forward option, i immediately disabled it. and later also i was not very confident with this case and have the passwords changed continuously. all strongest passwords :D

ps:keep reading part 3 continues!
